Start disable Internet Explorer before it´s to late

Stone, old, mottled

Internet Explorer 11 will go end of life on June 15, 2022. This means no more security patches for the web browser. Web browsers should absolutely be security updated to mitigate incidents. Edge has been there for years now and a really good replacement. So lets get rid of the old and in with the new!

Deploy Microsoft Edge

First, make sure you deploy the latest and greatest web browser Microsoft Edge. This browser is not only available on Windows. Also on MacOS, Android, iOS and Linux. So make sure you give your users the same experience on all platforms. One simple way to deploy Edge and also keep it up to date, is to use Intune.

  1. Sign in to the Microsoft Endpoint Manager admin center.
  2. Select Apps > All apps > Add.
  3. In the App type list under the Microsoft Edge, version 77 and later, select Windows 10 and Later.
  4. Accept the default settings.
  5. Select the appropriate channel for your users. normally stable
  6. Keep the language to Operating System Default. (select if you need to deploy a specific language)
  7. Finish creating the app deployment and assign it to your targets.

Internet Explorer Mode

If you still have sites that don´t work in new browsers like Edge, there is a IE mode you can use as an interim solution. IE mode on Microsoft Edge makes it easy to use all of the sites your organization needs in a single browser. It uses the integrated Chromium engine for modern sites, and it uses the Trident MSHTML engine from Internet Explorer 11 (IE11) for legacy sites. You only need to add all sites that needs to run in IE mode to a list and deploy the setting. This can be done either by GPO or MEM Intune.

Enable IE Mode with GPO

  1. Open Group Policy Editor.
  2. Click Computer Configuration > Administrative Templates > Microsoft Edge.
  3. Double-click Configure Internet Explorer integration.
  4. Select Enabled.
  5. Under Options, set the dropdown value to
    • Internet Explorer mode if you want sites to open in IE mode on Microsoft Edge

  8. Open Group Policy Editor.
  9. Click Computer Configuration > Administrative Templates > Microsoft Edge.
  10. Double-click Configure the Enterprise Mode Site List.

End User Experience

If a user tries to open the disabled Internet Explorer, a message is displayed: This action is restricted…. (Would have been great if this message was editable. but NO)

If a user tries to open a page from Enterprise Mode Cloud Site List it will show a small IE logo in the addressbar to indicate running in IE mode:

To verify if the list has been deployed, open up Edge://compat/enterprise
